目前国内对于双卡智能手机的需求还是很大的，各种复杂的业务会涉及到双卡模块；而android标准的api又不提供对双卡的支持。导致国内双卡模块标准混乱，各个厂商各玩各的。目前我知道的双卡解决方案就有：mtk，展讯，高通，broadcom等

首先是最为应用广泛的mtk平台，国内山寨手机以及一些低端品牌双卡都是做的mtk的双卡解决方案

private static void initMtkDoubleSim() {try {TelephonyManager tm = (TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE);Class<?> c = Class.forName("com.android.internal.telephony.Phone");Field fields1 = c.getField("GEMINI_SIM_1");fields1.setAccessible(true);simId_1 = (Integer) fields1.get(null);Field fields2 = c.getField("GEMINI_SIM_2");fields2.setAccessible(true);simId_2 = (Integer) fields2.get(null);Method m = TelephonyManager.class.getDeclaredMethod("getSubscriberIdGemini", int.class);imsi_1 = (String) m.invoke(tm, simId_1);imsi_2 = (String) m.invoke(tm, simId_2);Method m1 = TelephonyManager.class.getDeclaredMethod("getDeviceIdGemini", int.class);imei_1 = (String) m1.invoke(tm, simId_1);imei_2 = (String) m1.invoke(tm, simId_2);Method mx = TelephonyManager.class.getDeclaredMethod("getPhoneTypeGemini", int.class);phoneType_1 = (Integer) mx.invoke(tm, simId_1);phoneType_2 = (Integer) mx.invoke(tm, simId_2);if (TextUtils.isEmpty(imsi_1) && (!TextUtils.isEmpty(imsi_2))) {defaultImsi = imsi_2;}if (TextUtils.isEmpty(imsi_2) && (!TextUtils.isEmpty(imsi_1))) {defaultImsi = imsi_1;}} catch (Exception e) {isMtkDoubleSim = false;return;}isMtkDoubleSim = true;}

可见，在TelephonyManager中提供了**Gemini的方法，可以用反射很方便地获取到相应的信息。

还有

private static void initMtkSecondDoubleSim() {try {TelephonyManager tm = (TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE);Class<?> c = Class.forName("com.android.internal.telephony.Phone");Field fields1 = c.getField("GEMINI_SIM_1");fields1.setAccessible(true);simId_1 = (Integer) fields1.get(null);Field fields2 = c.getField("GEMINI_SIM_2");fields2.setAccessible(true);simId_2 = (Integer) fields2.get(null);Method mx = TelephonyManager.class.getMethod("getDefault",int.class);TelephonyManager tm1 = (TelephonyManager) mx.invoke(tm, simId_1);TelephonyManager tm2 = (TelephonyManager) mx.invoke(tm, simId_2);imsi_1 = tm1.getSubscriberId();imsi_2 = tm2.getSubscriberId();imei_1 = tm1.getDeviceId();imei_2 = tm2.getDeviceId();phoneType_1 = tm1.getPhoneType();phoneType_2 = tm2.getPhoneType();if (TextUtils.isEmpty(imsi_1) && (!TextUtils.isEmpty(imsi_2))) {defaultImsi = imsi_2;}if (TextUtils.isEmpty(imsi_2) && (!TextUtils.isEmpty(imsi_1))) {defaultImsi = imsi_1;}} catch (Exception e) {isMtkSecondDoubleSim = false;return;}isMtkSecondDoubleSim = true;}

看样子有似乎也是属于mtk平台的解决方案，因为都有GEMINI_SIM_1属性,这种双卡方案只在联想278t上发现过；有两个TelephonyManager实例，根据getDefault方法获取

下面是展讯平台的（貌似市面上手机不多啊）：

private static void initSpreadDoubleSim() {try {Class<?> c = Class.forName("com.android.internal.telephony.PhoneFactory");Method m = c.getMethod("getServiceName", String.class, int.class);spreadTmService = (String) m.invoke(c, Context.TELEPHONY_SERVICE, 1);TelephonyManager tm = (TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE);imsi_1 = tm.getSubscriberId();imei_1 = tm.getDeviceId();phoneType_1 = tm.getPhoneType();TelephonyManager tm1 = (TelephonyManager) mContext.getSystemService(spreadTmService);imsi_2 = tm1.getSubscriberId();imei_2 = tm1.getDeviceId();phoneType_2 = tm1.getPhoneType();if (TextUtils.isEmpty(imsi_1) && (!TextUtils.isEmpty(imsi_2))) {defaultImsi = imsi_2;}if (TextUtils.isEmpty(imsi_2) && (!TextUtils.isEmpty(imsi_1))) {defaultImsi = imsi_1;}} catch (Exception e) {isSpreadDoubleSim = false;return;}isSpreadDoubleSim = true;}

这个没有展讯sdk的话还是很难找的吧？

下面是高通的：（貌似高通做的不咋的有些接口没有双卡实现啊）

public static void initQualcommDoubleSim() {
try {
TelephonyManager tm = (TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE);
Class<?> cx = Class
.forName("android.telephony.MSimTelephonyManager");
Object obj =mContext.getSystemService(
"phone_msim");
simId_1 = 0;
simId_2 = 1;Method mx = cx.getMethod("getDataState");
// int stateimei_1 = (Integer) mx.invoke(cx.newInstance());
int stateimei_2 = tm.getDataState();
Method mde = cx.getMethod("getDefault");
Method md = cx.getMethod("getDeviceId", int.class);
Method ms = cx.getMethod("getSubscriberId", int.class);
Method mp = cx.getMethod("getPhoneType");// Object obj = mde.invoke(cx);imei_1 = (String) md.invoke(obj, simId_1);
imei_2 = (String) md.invoke(obj, simId_2);imsi_1 = (String) ms.invoke(obj, simId_1);
imsi_2 = (String) ms.invoke(obj, simId_2);int statephoneType_1 = tm.getDataState();
int statephoneType_2 = (Integer) mx.invoke(obj);
Log.e("tag", statephoneType_1 + "---" + statephoneType_2);// Class<?> msc = Class.forName("android.telephony.MSimSmsManager");
// for (Method m : msc.getMethods()) {
// if (m.getName().equals("sendTextMessage")) {
// m.getParameterTypes();
// }
// Log.e("tag", m.getName());
// }} catch (Exception e) {
isQualcommDoubleSim = false;
return;
}
isQualcommDoubleSim = true;}

getPhoneType&getDataState 方法看了底层发现没有双卡实现，目前也不知道该咋办...
